To all {v7/,ont it 77mg/ concern:

Be it known that I, JOHN F. Aims, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Type-Holders for BOX-Printing Presses, of which the following is a specii, fication. i

My invention relates to a chase or typeholder for cylinder printing-presses, and especially' for presses designed for printing on wood or like surfaces. Its object is to provide a removable attachment to a printingpress cylinder which will permit the use of removable metal or hard-surfaced type and which will afford a simple, practical, and easily-operated means for securely locking the type in position.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which* Figure 1 is a side view holder. Fig. 2 is a transverse section of the holder. Fig. 3 is a plan view of the same. FigA is a longitudinal section on line :r x of Fig.

of my improved 1. Fig. 5 is a transverse section of the modied form of the holder shown in Fig. 6. Fig. 6 is a plan of a modified form of holder. Fig. 7 is adetail bf a strip used in Fig. 6. Fig. 8 is an end view of form-cylinder with holder applied.l Fig: 9 is a plan view of same.

A represents a segmental type-holder or chase adapted to be removably secured by any suitable means to the form-cylinderB of a printing-press. VThis holder is usually less than ordoes not exceed a half-cylinder in shape in order that it may be readily slipped on and oil' sidewise of the form-cylinder witl 1- lout disarrangement of the mounting of the atter.

T he holder is provided on its outer surface at the sides and ends with the respective y flanges 2 2', which may be integral with the plate or built up therefrom. In any event these flanges would not project beyond the plane of the printing-surface of the type, which latter are set and clamped in the area inclosed by the flanges in the following manner.

The surface of the holder along the opposite ends adjacent to the flanges 2 and in the direction of the length of the form-cylinder is channeled, as at 3, to furnish two undercut ledges 4 to hold the segmental spacing-i strlpe 5. 'These struis,\\'l1u:h extend circuml l ferentially of the holder, have a curvature corresponding to that of the holder and a length equal tothe circumferential distance between the end flanges 2 and have beveled or hooked underneath portions 6 at their ends to fit in the channels or grooves 3 and engage beneath the ledges 4.

In order to permit of the insertion of the strips into the channels 3, the latter are widened or enlarged toward each other at one end, as indicated at 7.

The several strips are beveled on their opposite longitudinal edges, as at 8, so that these edges converge inwardly when the strips are in position and operate to lock the type 9, which have correspondin ly-beveled portions 10. Thus with a line of type clamped between two strips or a strip and a side flange 2 on the holder the type will present aflared or dovetailed portion to the strips or the strip and flange and be held securely, while the undercut ledges 4 on the holder and the terminal hooks 6 on the strips allow the latter to be moved freely across the holder, but effectively prevent the strips or the type from bulging out when suitable clamping means are applied to the strips.

The type have concaved rear surfaces and conveXed outer surfaces corresponding t0 the curvature of the holder to enable the printing-surface properly to receive and apply the ink.

The strips may be of any desired width, dependent on the re uired space between the lines of type, whifih also run circumferentially of the cylinder. The final strip '5,- which is in the nature of a follower, has the inwardly-projecting radial lugs 9, fittingslots 10l in the holder and forming seats for the locking-screws 11, which are threaded in a side of the holder.

With the form set up the strip 5 is inserted and the screws 11 are tightened to securely bind the type in position against any'movement transversely of the holder. Movement of the type longitudinally of the holder in the spaces between the strips is `preven-ted by means of screws 12, fitting threaded perforations 13 in the ends of the holder. Usually a follower block or blank 14 is inserted at the ends of each line of type to receive the pressure of the screws 12, and a number of holes 13 is supplied, so that whatever width of strips or width of type may be' used a screw can always be adapted to engage a line of type and insure a proper lock. Thus it will IOO be seen that the respective side and end screws j 11 12y operate so that one set clamps the strips in a direction transverse to their length and the other clamps the type in the direction of the length of the strips and absolutely lock the type on all sides,whereby displacement of the type or disarrangement of the form become impossible-a most essential feature in b ox-printing where the form is subjected to exceptionally` hard usage on account of the unyielding character of the substance printed on.

In order to guide and assist'the compositor in set ting up and spacing his type or proportioniiig his lines, the strips may be provided with graduations, as 15, running crosswise of the several strips. Y

In Fig. 6 is shown a modiied form of holder, in which the ends of the strips 5a are adapted to engage in grooves in the end flanges 2a and to be siidable transversely of the plate and guided in these grooves. The walls of the grooves adjacent to the side of the plate carrying the screws 11a are cut away to let the strips be inserted into or taken out of the holder. The slots l0a extend across the plate A and are enlarged at one end, as shown at 10", to permit headed lugs or beveled projections 16, carried on the under side of all the strips, to pass through. The sides of the slots are tapered divergently inward corresponding with the tapered heads 16, so that the latter after passing throu h the larger openings 1()b are substantially ush with the inner periphery of the plate, so as not to interfere with the close tit of the plate on the form-cylinder. The heads prevent the movement of the strips radially of the plate, except when the heads and openings 10b register, and at the saine time they allow the strips to be easily shifted crosswise of the plate. The surface of the plate along each side of the slots 10u is channeled, as shown at 10, to provide seats for the thin metal plates 17, which may be placed in between the strips to lie lush with the plate A and to support the smaller type, which might otherwise fall through the slots or be thrown out of line thereby. This st-yle ol holder is particularly adapted for heavy printing, since the headed lugs 16 effectually prevent any bulging ofthe strips or type.

1t is to be especially observed that in both forms of holder shown the spacing-strips and the lines of type run circumferentially of the cylinder when the holder is placed on the cylinder.

Vooden boxes generally have the grain ot the wood ruiming around the box, and the printing inust be dom` on the wood with the lines ol" type ruiming with the grain. Conse- (uently in a cylinder box-printing press the lines of type must run cireuniferentially of the cylinder and there must be no break in the printing-surface. T he feeding mechanism of a box-printing press is entirely different from the feed mechanism of jresses for printing on cloth orpaper. Inthe ox-printing presses of the type with-which my improved form is used the board to be printed on is brought into contact with the brand by a lug on a feeding-chain; but the moment the brand is indented into the wood the further movement of the board through the press Ais done by the brand itself. Thus it is readily erceived that itis necessary to have the various lines and words in the several lines break joint, as it were, in order to produce a continuous printing-surface and a smooth feed, which could not be done if the- .spacing-strips and lines ran lengthwise of the printing-cylinder. By ruiming the lines circumferentially and having the printing-surface continuous there is no danger of splitting or cutting the wood.

If the spacing-strips extended longitudinally of the printing-cylinder, it is obvious there must be a break in the printing-matter the entire length and corresponding with the width of the strip.

With the spacing-strips extending circumferentially, as here shown, the varying width of the letters as they are placed side by side around the surface to make the reading-matter occasion no inconvenience in locking the forni. While the wid-th may vary, the length of all letters of the saine line is the same.

By having the holder separate from the cylinder and easily attachable thereto and removable therefrom by means not necessary here to be shown and by having the removable and interchangeable type and spacingstrips and by making the printing-surface raetically continuous by suitably positioning the letters and words in the several lines l provide a valuable adjunct to box-printing presses which allows the same holder and aecompanying accessories to be used for a great variety of styles and sizes of forms and brands.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A type-holder for cylinder-presses consisting of a plate curved in cross-section to conform to a form-cylinder, segmental s acing-strips carried by and slidable on an extending circumterentially of said plate, removableI type interposed between said stri s and means operatable from one end of t e curved plate for clamping the type and strips on said plate.
